The XtraFlex Duet LED Music Light features dual goosenecks & dual Super LED lights with separate switches and best of all...no bulbs to replace! This can be used in either a clip-on or freestanding configuration. The included AC adapter provides an added benefit for orchestras and bands using controlled lighting. Best of all: the Duet2 lights more than two pages of sheet music!

Features:

• Four different light level options• Dual flexible arms provide infinite maneuverability• Two lighting heads, each containing two large LEDs• Sensor switches on each lighting head require just a tap to turn on one or both LEDs• Optical grade lens provides evenly distributed light with no hot spots• Easily bends to compact position for storage• Extra strong clip grips almost anything, or use free standing• Offers 20 hours of continuous use on 3 AAA batteries• Powered by included AC adapter (110-240 volts, included) or 3 AAA batteries (not included)

These really put out. I'm amazed that so much light is emitted by something powered by 3-AAA batteries that last as long or longer than the 20 hours that they claim. The goosenecks stay right where you put them and the clamp holds fast. I highly recommend these. I even used them on Halloween as lighted antennas after clamping them on the back of a baseball cap!
